本组练习:用广角 + 小光圈让前景、中景、后景同时清晰,并在三层之间安排人物、视线与纵深走位,让一个画面同时讲几件事。| 配套教学:L02-04-深焦与多层调度 | 规范:写作规范
画风默认使用开关 A(风格化写实 CG)。如改用 2D 动画,删掉所有焦段、光圈、景深词。
练习1:慢棋与快风筝——三层深焦单图生视频(难度 ★)
目标:先学会搭一个"三层都清楚"的画面:前景棋盘、中景下棋的老人、后景公园里放风筝的孩子。视频里只让中景动一下,后景保持循环小动作。意图:让观众感到老人的棋下得很慢,而外面的世界跑得很快。

图1 关键帧:
A wide shot in a quiet old park pavilion on a windy spring afternoon, three layers all in sharp focus.
Foreground: a wooden Chinese chess board with round pieces on a stone table at the bottom left of the frame, about 0.6 meters from the lens.
Middle ground: an original elderly man in his seventies with a white crew cut, a navy Mao-collar jacket and cloth shoes, sitting at the stone table
on the center-left about three meters away, one hand on his knee, studying the board.
Background: beyond the pavilion's open arch on the right third, about twenty meters away, a small child in a red jacket runs across the grass
pulling a kite string, a bright yellow kite high in the sky.
Camera at seated eye level, 24mm lens, f/11, deep focus: the chess pieces, the old man's face and the running child are all sharp.
Lighting: soft warm afternoon sun from frame right falling across the grass outside, cooler shade inside the pavilion, the outside noticeably brighter.
Stylized semi-realistic 3D CG rendering, feature-film animation quality. Aspect ratio 16:9.中文释义:远景,公园凉亭,三层全部清晰。前景:画左下石桌上的象棋盘,离镜头 0.6 米;中景:画面中偏左约三米外,原创老人坐着看棋;后景:右三分之一的拱门外约二十米,穿红衣的小孩拉着风筝线跑过草地,黄色风筝高飞;坐姿视线高度、24mm、f/11 深焦;画右暖阳照在亭外草地上,亭内是较冷的阴影,外面明显更亮。
【图生视频 · Seedance】
【素材分工】@图片1 为首帧,锁定人物身份、服装、三层空间布局与深焦效果。
【画风】风格化写实三维CG质感,电影级布光。
前景的棋盘、中景的老人和后景草地上的孩子始终全部清晰。老人盯着棋盘想了很久,慢慢伸出手,捏起一枚棋子,在半空停了一下,轻轻放下,又把手收回膝上。后景拱门外,红衣小孩拉着风筝线来回奔跑,黄色风筝在风里上下飘动。镜头固定,不移动。亭外暖阳明亮,亭内阴影偏冷。结尾停在老人重新看着棋盘、远处风筝高飞的画面上。
【声音】风吹过凉亭的呼呼声,棋子落在木棋盘上清脆的一声,远处孩子隐约的笑声,几声鸟叫,无配乐。
【约束】保持人物脸型、服装不变;前中后景始终清晰,不虚化;孩子始终在拱门外,不跑进凉亭;棋子上的字模糊不可读;不要字幕、水印、Logo。
时长:6秒参数:时长 6 秒 | 画幅 16:9
【检查点】
三层是否同时清晰,后景孩子是否没有被虚化
主动作是否只有老人放棋子,孩子只是循环奔跑
亭外亮、亭内暗的对比是否把视线引到后景
【常见问题与修复】
| 现象 | 修复 |
|---|---|
| 后景孩子被虚化成色块 | 首帧写 "the running child is sharp and readable",视频约束写"前中后景始终清晰,不虚化" |
| 棋子上出现错乱文字 | 写"棋子上的字模糊不可读",或棋盘不正对镜头 |
| 孩子跑进凉亭 | 写"孩子始终在拱门外的草地上" |
| 老人一直不动 | 动作只写一个"捏起一枚棋子、放下",并加呼吸与眨眼 |
练习2:小面馆的一家三口——三层人物调度(难度 ★★)
目标:三个人物分占三层并左右错开,用一次"视线连接"把三层串起来。意图:让观众感到这一家人各忙各的,却都在彼此的视线里。

Foreground on the right third, about one meter from the lens: the manager seated at a large dark desk in three-quarter back view, his shoulder and head large in the frame,
a heavy crystal paperweight and a desk lamp on the desk.
Background on the left third, about ten meters away at the far end: the young employee standing just inside the open double door, small in the frame, holding the white envelope at her side.

Using the characters from image 1 and the exact same camera position, lens and office as image 2:
the young employee now stands in the foreground on the left third right beside the desk, about one meter from the lens, large in the frame, from the waist up,
her hand placing the white envelope flat on the desk, looking down at him.
The manager remains seated on the right, now leaning back in his chair, looking up at her, appearing smaller than her in the frame.
24mm lens, f/11, deep focus: both of them and the empty doorway far behind are sharp.
Lighting: warm desk lamp in the foreground, cool window daylight stripes across the floor behind them.
Keep the faces, hairstyles and outfits exactly as in image 1.
Stylized semi-realistic 3D CG rendering, feature-film animation quality. Aspect ratio 16:9.中文释义:首帧是长长的办公室,前景画右是上司三分之四背影坐在大桌后,肩和头很大;后景画左十米外,年轻职员站在门口,很小,手里拿着白信封;24mm、f/11 深焦。尾帧机位相同,她已走到前景画左桌边,腰部以上,把信封平放在桌上,低头看他;上司靠回椅背抬头看她,在画面里比她小;远处门口空着,依旧清晰。

镜头2:镜头切至新娘的正面近景,85毫米,浅景深,身后的宾客虚成金色光斑。她举着酒杯的手停在半空,嘴唇抿紧,眼睛一直看着画右远处,轻轻吸了一口气。欢呼声变远、变闷。
镜头3:镜头切回与镜头1完全相同的固定深焦全景,三层全部清晰。后景门口的男人朝新娘微微点了一下头,转身走进明亮的走廊,消失在门外。前景的新娘慢慢放下酒杯,中景的宾客仍在欢笑、坐下。镜头固定,停在空荡荡的明亮门口与前景新娘的侧脸同框的画面上。宾客的笑声重新响起,盖过一切。
【锁定】光线:宴会厅吊灯暖金色,门外走廊冷白光始终在画右后景;新娘始终在画左前景、面朝画右,男人始终在画右后景门口;镜头1与镜头3机位、焦段、构图完全一致,只有镜头2是浅景深近景。

后景男人离开这个动作是否清楚可读
【常见问题与修复】
| 现象 | 修复 |
|---|---|
| 镜头3 构图和镜头1 不一样 | 写"镜头切回与镜头1完全相同的固定深焦全景",并在【锁定】里重复 |
| 后景男人太小,脸部漂移 | 他只做剪影级动作(点头、转身、走出),不写表情 |
| 宾客走动挡住门口 | 写"宾客只在原位举杯、欢笑、坐下,不走动" |
| 镜头2 背景也清晰 | 镜头2 单独写"85毫米,浅景深,身后的宾客虚成金色光斑" |
练习5:照相馆的最后一个下午——四镜头多层调度(难度 ★★★★★)

观众能否从画面看懂"前景在签转让,中景和后景都不知道"
镜头3 的主动作是否集中在老夫妇进门,店主和学徒只是小动作
镜头4 店主的情绪是否靠摘眼镜、擦拭、换上笑容表现
【常见问题与修复】
| 现象 | 修复 |
|---|---|
| 买家整个人出现在画面里 | 写"买家只露出画右边缘一只黑西装袖口的手,身体在画外" |
| 后景老夫妇被虚化 | 首帧写 "the couple outside are sharp",视频写"所有镜头前中后景都保持清晰" |
